🐛 Bug Fixes

Qwen AI Silent Content Drop

• Fixed content from non-standard phases being silently dropped
• Thinking mode now defaults to enabled (enable_thinking !== false)
• auto_thinking always set to true for better reasoning

Qwen Context Loss

• Multi-turn conversation history converted to single prompt via messagesToPrompt
• Full context preserved across requests without relying on provider session state

Credential Encryption Toggle

• credentialEncryption config field now properly wired to backend
• setCredentialEncryption persists to backend config
• Encryption disabled returns plaintext when toggle is off

Data.json Performance

• Logs migrated to separate logs-data.json store
• LogManager uses buffered writes with 2s flush interval

• New test suites: session-manager (27 tests), log-buffering (5 tests)
• Z.ai chat ID caching for account-level reuse
